Abstract
The carotid blood distribution has been evaluated using radioactive microspheres in 13 regions of the head and in 10 cerebral structures of rats, and the intracerebral distribution of blood has been studied comparatively after injection of microspheres into the left cardiac ventricle or into the internal carotid artery. The principal results indicate that the cerebral tissue is not supplied by the external carotid blood, whereas about 30% of the internal carotid blood goes to the brain, and that the pontomedullary region receives its blood mainly from the vertebral artery.
